I bought from a primary homeowner in Indianapolis metro area who took really good care of this home (I did live in this house and rented it out when I moved back to California) and from a flipper in Indy more recently.As far as primary homeowners, they can range from taking really good care of the house to someone who has a lot of deferred maintenance - I renovated a local property that had a lot of issues.
